Praxistipusingtheexampleofthe”connectionofapressuretransmitter-1..7bar”:Here the
indication on the pressure transmitter is clear (-> -1 bar) relative to the ambient pressure The
adjustment of the pressure transmitter in the controller is carried out using absolute pressure values
(the absolute pressure cannot be negative). In order to parameterise the above pressure transmitter
with the relative pressure indication - 1 bar (at 4 mA, i.e. 0 V) at 7 bar ( at 20mA, i.e. 10 V) the ambient
pressure (1 bar) must be added. The entry is carried out as follows: 0..8 bar.
